ELECTRIC FITTING.

Specification of Letters Batent.

Application led March 21, 1917. Serial No. 156,493.

To all whom it may concern.'

Be it known that I, FRANK V. BURTON, a'citizen of the United States of America, and residing at Bridgeport, in thecounty of Fairfield and State of Connecticut, have invented a certain new and useful Improvement in Electric Fittings, of which the following is a specification.

My invention relates to electric fittings and particularly to fittings of the type adapted to be secured at the end of a wire conduit, and the object of my invention is y to provide an improved construction of the fitting which facilitates the adjustment thereof on the conduit, particularly with relation to the lead wires drawn through the latter and secured to the fitting.

In the accompanying drawing,

Figure 1 is aside elevation of an electric fitting in whichv my invention is embodied in one form;

Fig. 2 is a section therethrough on the line 2-2, Fig. 1; j

Figs. 3|and 4 are vertical sections on the lines 3-3 and 4 4, Fig. 2, respectively.

In the accompanying drawing I have illustrated my invention ,embodied in a fitting of candle socket type adapted to be mounted uponA the end of a wire conduit 10. The socket comprises an insulating body 11 at one end of which are mounted the lamp terminals 12 and 13. Cverlying the base flanges 14 of the screw shell contact 12 is a yoke 15 with downwardly angled lug 16 tapped 1to receive the binding screw 17 for the wire 18. The terminal 13, constituting, the center lamp contact, is also integral with the downwardly extending lug 19 tapped to receive the second binding screw 20 for the other wire 21. At the end of the body 11, opposite that at which the lamp terminals are secured, is a yoke 22 the oi'set feet of which are secured to the body 10 by screw bolts 23, the heads ofv which are countersunk below the level of the lamp terminals. The yoke 22 carries a screw thimble 24 adapted to be screwed upon the threaded end of the wire conduit l0 and is held in adjusted position by a set screw 25.

The fixture to which a socket of this ty e is attached is Ordinarily wired prior to the assembly lof the socket therewith and the wires are drawn through into the position indicated by dot and dash lincs'26 in Fig. 3.

In sockets of the present type it has been',l

common practice to provide the securing nipple with apertures through which the wires are necessarily drawn out before the socket is screwed to the wire conduit. As a result, the wires become twisted in the conduit when the socket is screwed down upon the latter. This is an objectionable pract1ce. made it possible to avoid this practice. To this end the body 10 is pierced at 27 in register with the bore of the conduit so that the wires may be -run up therethrough during the screwing down of the socket on the conduit. Since the wires may projectupward-beyond the center contact, thelatter is also apertured at 28 in order to permit the wires to pass therethrough. It is obvious that the socket may be adjusted -andscrewed down upon the conduit while the wires lie in the passages 27, 28 and thereafter be fished out and secured to the `wire terminals, as illustrated in full lines in Figs. Land 3. j While I have shown my invention applied to a candle socket, it is 'clear that the same construction is valuable in any7 tting adapted to be secured to a wire conduit in this fashion and I do not limit my invention to the particular application thereof shown or tothe details of construction indicated which may be variously modified without departing from what I claim as my invention.

I claimz.-

1. A conduit fitting having an insulating body, means for securing the same to the conduit, and exterior wire terminals on the sides of said body, said body being pierced -n register with the conduit to permit the free passage of the lead wires therethrough dur- Ing the securing of the itting'to the conduit.

2. A conduit fitting having an insulatin body, exterior wire terminals on the sides o said body, a screwnipple carried by said body for securing the same to the conduit, said body being pierced in register with said` nipple to permit the passage of the wires therethrough during the operation of screwing the nipple on the conduit.

3. A conduit fitting having an insulating body, a screw nipple carried by said body for securing the same to the conduit, a terminal having portion thereof alined with said conduit, said body and terminal being pierced in register to permit the passage of the wires therethrough during the opera- By my present construction I have tion of screwing the nipple to the conduit spaced from'the body by en open yoke piece together With exterior Wire terminals on the through Which the Wires are accessible for sides of said body. A fishing out after the fitting is installed.

4. A conduit tting having an insulating ln testimony whereof l have signed my 15 5 body, exterior Wire terminals on the sides name to this speciication, in the presence of said body, carried by said body. for seof two subscribing Witnesses.

curing the same to the conduit, said body being pierced in register With said nipple FRANK V' BURTON' to permit the passage of the Wires there- Witnesses:
